The invention relates to an intelligent sailing ship active stabilization device and a control method, a shaftless rim propulsion device is installed on a fin stabilizer close to the fin root, and the ship active stabilization device is controlled according to the rolling angle, the angular velocity information and the angular acceleration information collected by a ship attitude sensor and the ship navigational speed information obtained through a DGPS system. The rolling motion of the ship is reduced by controlling the fin angle of the fin stabilizer and the rotating speed of the shaftless rim propelling device to generate resistance moment. Different control methods can be adopted according to the navigational speed. When the ship speed is lower than a certain value, the lift force of the fin stabilizer is low, and ship rolling is reduced through thrust generated by the shaftless rim propeller; when the ship speed is higher than a certain value, the lift force of the fin stabilizer is high enough, and the fin stabilizer is used for generating resistance to rolling; when the ship speed is between the two speeds, the fin stabilizer and the shaftless rim propeller jointly generate resistance to achieve the stabilization effect, the good stabilization effect at the speed from zero to the full speed is achieved, and the fin stabilizer is wide in applicability, low in energy consumption, not prone to abrasion and high in durability.
本发明涉及一种智能航行船舶主动减摇装置及控制方法,在减摇鳍靠近鳍根部安装无轴轮缘推进装置,根据船舶姿态传感器采集的横摇角度、角速度信息和角加速度信息和通过DGPS系统得到的船舶的航速信息,通过控制减摇鳍的鳍角和无轴轮缘推进装置的转速产生抵抗力矩减小船舶的横摇运动。本发明可以根据航速采取不同的控制方法。当船速低于一定值时,减摇鳍升力低,利用无轴轮缘推进器产生推力减小船舶横摇;当船速高于一定值时,减摇鳍升力足够高,利用减摇鳍产生抵抗横摇的抵抗力;当船速介于两者之间时,减摇鳍和无轴轮缘推进器共同产生抵抗力达到减摇作用,实现了零到全航速下的良好的减摇效果,适用性广,消耗能量低,不易磨损,耐用性强。
